The OP and myself are having issues with the settings in the PVR-150 tuner,
not with our TV. Everything looks fine on my TV from sources other than the
PVR-150. It is the brightness, contrast, color settings of the tuner itself
that are off. The only way to adjust them is to do so while that tuner is
recording. Is there someway to route a DVD to the coax input on the PVR-150?
If I route the DVD player through the svideo input on my PVR-150, and adjust
that will those settings apply to the coax input also? It seems like they
wouldn't because they would be setup as different inputs in MythTV.
